The BS schedules the users to completely or partially offload tasks.
The users with complete or partial offloading respectively offload a fraction of or all input data to the BS, while the users with partial or no offloading respectively compute a fraction of or all input data using local central processing unit (CPU).
The channel is assumed to be frequently flat.
Due to the small latency of cloud computing and small sizes of computation results, the time of cloud computing and downloading from the BS is negligible compared to the time of mobile offloading and local computing [1]}.
